I posted another thread, assuming Chargery BMS was reporting correctly and my cells falling.
After pulling the lid on my battery and measuring with DVM, I see all 4 cells @ 3.322V and 3.321V. (Take a look at what chargery is reporting for my voltages, only -3Ah from full (I use 520Ah as full for 560Ah max capacity bank). This was after the battery had sat for 10 hours @ 14.10V to let the balancer do its thing. Since the reported voltage dropped so fast and voltage differential went wonky, I had assumed my battery was on death's door.
For 18 months, I've been powering the pack through the voltage taps. (my camper sits hibernating most of the time).
External power will come from this battery. I don't have another battery to power.
Anyhow what does the conventional wisdom say I should do? Is there another low-draw BMS which energizes heavy contactor?
Thank you!
Doug
